I IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 180,392, dated July 25, 1876; application filed June 23, 1876.

To all whom it may concern:

Be it known that I, JOSHUA TURNER, of Gambridgeport, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Spring Bed-Bottoms; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference'being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

In such drawing, Figure l denotes a top View, and Fig. 2 an end elevation, of a springbedfoundation constructed in accordance with my invention. Fig. 3 is a vertical and transverse section taken through one of the slatsuspending rods, to be hereinafter described.

The object of my invention is to produce a simple and cheap, as well as a durable and effective, spring foundation for a bed; and my invention consists in the peculiar construction,

combination, and arrangement of parts, as hereinafter described and claimed.

In the said drawing, A denotes a rectangular frame, consisting of the side bars a a and the end bars b I), the said bars being composed of wood or other suitable material, and jointed together in the usual manner. Each of the. end bars b has formed on its top surface a series of transverse slots or gains,77 o c, Sto., the same being formed of a width equal to or a little greater than that of the slats d d, &c., and of depth somewhat greater than the thickness of the slatsthe latter being made of thin flexible wood. Y

Within each outer vertical face of the end bars b, andextending longitudinally thereof, I form a channel or groove, f, having a depth of about one-half an inch. Through each of these channels, longitudinally and near the center thereof, a rod, g, passes, such rod having a length corresponding with the length ofthe channel in the end bars, and extending through holes formed horizontally through the series of slats, the rods so arranged and supported serving to hold the series of slats suspended near each of their ends, the open channels or grooves permitting the rods to vibrate or move laterally, to allow the desired iiexibility or yielding of the slats while under pressure, the depth of the grooves being such as to arrest the movements of the slats when they have reached the desired degree of flexure.

It will be evident that the bars g might be made in sections, so each slat might bev suspended and vibrate independently; but I prefer the method shown in the drawing.

In applying the slats to the frame in my improved manner, the rods g g are first inserted in holes in one of the side bars. The slats having been laid in the slots in the topv of the bars, each rod is to be forced along its channel f in the end bar, and through holes formed widthwise through the slats, the rods being supported in the channel in the end bars, and not extending into the side bars, the whole being so arranged as to bring the top of the slats on the same horizontal plane with the top surface of the frame, the rods being so disposed as not to come into contact with a mattress or bed when laid on the frame. Thus it will be seen that all of the slats are suspended at or near their ends upon the two rods g g, and the latter are disposed within the channels, which allow the slats to have the requisite degree of ilexile movement, and that provision is made for arresting the slats when the proper degree of flexibility is reached. I

By my arrangement, should the slats become sprung or sagged by use, by simply withdrawing the rods g g the slats may be readily removed and reversed, and the rods again passed through the same, whereby the parts will become again firmly connected.

Having described my invention, what I claim is- 1. The improved spring bed-bottom, as described, the same consisting of the bars a a and b b(the bars b being 4formed with the gains o and channels f,) the slats d d, &c., and

rods g g, the whole being constructed, com- Ar\r n cross-bars of the frame7 as shown and de- In testimony that Iolavm the foregoing as scribed. my own invention I affix my signa-ture in 3. The combination of a series of slats suspresence of two Witnesses.
